Parts of both countries are experiencing the most severe drought since record-keeping began nearly 105 years ago, meteorological officials in Pyongyang and Seoul said Tuesday.

The protracted drought is heightening worries about North Korea’s ability to feed its people. Two-thirds of North Korea’s 24 million people faced chronic food shortages, the United Nations said earlier this month while asking donors for $198 million in humanitarian aid for the country.

Even in South Phyongan and North and South Hwanghae provinces, which are traditionally North Korea’s “breadbasket,” thousands of hectares (acres) of crops are withering away despite good irrigation systems, local officials said.
